 Drawing OpenGL ES primitives.
  - drawPoint
  - drawLine
  - drawPoly
  - drawCircle
 
 You can change the color, width and other property by calling the
 glColor4ub(), glLineWitdh(), glPointSize().
 
 @warning These functions draws the Line, Point, Polygon, immediately. They aren't batched. If you are going to make a game that depends on these primitives, I suggest creating a batch.
